* Added the first LLVM unittest -- DenseMap.
* Updated mkpatch utility to include llvm/unittests dir
* Added top-level target "unittests" to run all unittests

llvm-svn: 61541

* Removed gtest_main.cc: we have our own main() elsewhere
* Simplified the Makefile as we don't need SOURCES

* Moved the internal header to gtest/internal/
* Simplified the Makefile to remove -I param to CPP.Flags

* Updated README.LLVM with all the steps I took to massage GTest to
  work in LLVM so far

Also added Makefiles at every level of the directory tree to properly recurse
to Google Test and build it as a library (original Makefiles by Talin).

arguments (pointer arguments only) are only dereferenced
and so do not escape.  Mark such arguments 'nocapture'.

  This makes some 64-bit operations legal.

constants, since doing so is irrelevant for aliasing
purposes.  While this doesn't increase the total number
of functions marked readonly or readnone in MultiSource/
Applications (3089), it does result in 12 functions being
marked readnone rather than readonly.
Before:
  readnone: 820
  readonly: 2269
After:
  readnone: 832
  readonly: 2257
